DIY Crawlspace Encapsulation

A crawlspace that isn't encapsulated

Do you feel confident taking on the project of encapsulating your property’s crawlspace? If you want to do this job on your own instead of hiring a professional like those on staff at Chad Love Services, it is possible. However, you need to be careful and diligent and follow directions.

These steps will walk you through how to do it, what you need, and more. It takes about 8 to 10 hours for a team of two to do a 1,000 square foot area, on average. 


  • Flashlight
  • Utility knife
  • Drill with masonry bits
  • Measuring tape
  • Work gloves
  • Protective eye wear
  • Trash bags
  • Disposable breathing mask
  • Knee pads
  • Marker
  • Crawlspace vapor barrier
  • Vapor barrier seam tape
  • Double-sided construction tape
  • Termination bars 
  • Concrete screws 

Step #1: Prep The Crawlspace 

Clean out the crawlspace first, to prepare it for encapsulation. Clean away old poly, old/wet insulation, sharp rocks or other debris. Check on the state of wires, if there is any standing water, and make sure the wood is not rotting. 

Step #2: Work On Verticle Walls 

Do the vertical surfaces first, like foundation walls. Apply tape to the masonry wall and apply the vapor barrier by unrolling it along the tape. Secure it to the concrete with a mechanical fastener like termination bars. Tape everything down on columns and pipes with seaming tape and do them in small sections. 

Step #3: Roll Out Vapor Barrier

Roll out the vapor barrier to cover the surface of the crawlspace, running up against walls to overlap every seam by at least six inches. Tape down all seams with seaming tape.
